The present invention is a photoelectric switch that can automatically turn on or off the security light or street light according to the ambient brightness according to the sunrise, sunset or weather during the day, such as security lights, street lights, etc. It is possible to turn off the lights automatically, and in parallel with this, every day changes depending on the season of the year, and the sunrise time of different time zones (breaking time 30 minutes before sunrise and after 30 minutes after sunset) The calendar timer circuit of the one-chip CPU, which has been set and memorized in advance, automatically flashes the security light and the street lamp in the exact time zone, and at the same time, the point and the light off time can be easily changed from the outside according to the ambient brightness conditions or the need. It is possible to turn on / off the security light, street light, etc. exactly at the required time zone by operating. It improves reliability and certainty so that the effect of power saving can be greatly expected, and it can be installed in a simple operation that connects two wires in series to security light, street light, etc. A photoelectric switch combines a calendar timer switch.

In general, it is well known that security lights and street lamps are installed in security vulnerable areas such as streets, alleys or human security.

However, in the conventional case, by using a general manual switch or by using a photoelectric method using a photosensitive method such as a CdS photosensitive sensor, the photosensitive amplifier operates according to the ambient brightness, for example, the ambient brightness due to sunrise or sunset. As a result, a security light and a street lamp are turned on or off. In the case of the general manual switch of the electronic device, a manager or a resident artificially turns the switch on and off to indicate a security light or a street lamp. In the latter case of using a photoelectric switch, it was exposed to the surrounding environment or windy weather after a considerable time after installation. Inevitably, there is a case where the contaminated photoresponder site is contaminated, and thus the photoresponder malfunctions. In addition, the system is inoperable and unable to perform its functions, resulting in operational problems such as security lights, street lamps, unlit or unstable lights. There is a problem that the inspection and maintenance of the contamination status of the photoresponder site needs to be checked from time to time, resulting in uneconomical defects such as requiring a lot of manpower and expenses for maintenance. In addition to the phenomenon that the state of unnecessary lighting is maintained even in bright daylight, a lot of power is wasted.In addition, in the installation work, the power of the photoelectric switch must be unplugged and installed separately from the street light power. This tricky and complicated, skilled technique On the other hand, there have been various problems such as unstable operation after installation or incorrect wiring, or expensive photoelectric switch may be damaged.

This orphan is designed to solve these problems, and the calendar timer circuit that memorizes the average morning and evening timetables that change according to the seasons for one year in each region is changed according to the season. In addition, it is possible to precisely turn on / off the security lamps and street lamps in the night time zone, and at the same time, according to the correction of the lighting time according to the installation of high obstacles near the night time zone or the brightness of the surroundings due to the weather, If it is necessary to turn on or off the street lights, the CdS can be turned off and on regardless of the calendar timer and off time memory status. The effect of power saving can be expected by eliminating the waste of power. If a deviation occurs, it can be readjusted as required by the button operation on the outside of the main body. The 1Hz oscillation circuit of the blackout compensating oscillation circuit allows only the calendar timer circuit to operate and stops all other circuit operations, significantly extending the discharge time of the built-in battery. In the installation, it is possible to replace the existing light switch in the position of the existing flashing switch which is several meters down from the security light by adopting the two-wire connection method connected in series with the security light to the two-wire power line connected to the security light and the street light. Easy for the unskilled person to install without the need for separate wiring work That allows you to quickly and perfectly, with no connection five examples will be described in detail based on the accompanying drawings, it follows.

That is, FIG. 1 shows a detailed circuit diagram of the present invention, and FIG. 2 illustrates the connection and installation state of the present invention.

As shown in Figs. 1 to 2, the calendar switch A of the present invention is provided with a circuit breaker 2 and an external auto-manual switching switch 3 installed at two power sources l1 and l2. It is connected in series with discharge lamps (hereinafter referred to as "discharge lamps") 1 of security lamps.

As shown in FIG. 1, the transformer 1 and transformer PT for power supply are wound to the primary side of the same iron core with respect to the two power strands l1 and l2. After constructing the transformer 4 in the structure, the primary winding L1 of its current transformer CT is connected in series with the switching element TRIAC 5, and the primary winding L2 of the transformer PT is A power generation and switching circuit section 6 connected in parallel with the switching element 5 through the voltage drop capacitor C1 is constructed, and is connected to the secondary side winding L3 of the current transformer CT and the transformer PT thereof. Connect the bridge rectifier circuit 7 to rectify the AC current to DC, then obtain the rated voltage of the DC power through the constant voltage circuit 8 to display the calendar timer circuit 9, date and time setting described below. While supplying to each power source such as the circuit unit 10, the auto-off detection circuit unit 11 and the power failure compensation clock generator 12, power generation and The AC component induced in the current transformer CT of the switching circuit unit 6 and the secondary side L3 of the transformer PT is directly clocked through the resistor R2 to the clock signal of the calendar timer circuit unit 9 (the commercial frequency of the AC component is 60 Hz). ), And the voltage of the constant voltage circuit unit 8 is separately charged to the battery (BATT) to be used as a power failure compensation power supply in case of power failure.

Therefore, power generation, and the switching circuit 6 is powered two-wire (ℓ _1), relative to (ℓ ₂₎ and to be connected to the current transformer (CT) and the transformer (PT) in series, the switching element 5 is a current transformer (CT) Is connected in series with the primary side L1 of the circuit and connected in parallel with the primary side L2 of the transformer PT so that the switching element 5 is operated (ON), that is, when the discharge lamp 1 is lit. AC power supply line (1)-discharge lamp (1)-circuit breaker (2)-primary side (L1) of current transformer (CT)-switching element (5)-power line (1) In the state where the power flows to the secondary circuit L3 of the transformer 4 using the single iron core and the switching element 5 is turned off, that is, the discharge lamp 1 is turned off. The power source (AC) is the power line (1)-Discharge lamp (1)-Circuit breaker (2)-Primary side (L1) of current transformer (CT)-Primary side (L2) of transformer (PT)-Voltage drop capacitor (C1) -Voltage is induced in the path of the power line l2 [Operation in reverse order] to supply power. It is.

Therefore, the power supply (l1). (L2) of two strands is always used to discharge the current (CT) and transformer (PT) on the secondary side (L3) connected in series regardless of the point and off state using the discharge lamp (1). Except for the state, the voltage is induced to ensure the certainty of the drag operation.

The calendar timer circuit 9 is a one-chip CPU with integrated functions such as program memory, data memory A / D converter, and I / O. The average morning and evening timetables of 365 days (one year period) according to the season are inputted. The built-in memory stores the trigger signal at the time of the discharge lamp (1), the corresponding evening of the month and the day when the lights are off, and this signal is supplied and switched through the forward diode (D1) and the resistor (R2). The triac driving photocoupler that triggers the switching element 5 of the circuit unit 6, that is, the drive circuit unit 13 is operated, thereby triggering the switching element 5 to be turned ON to operate the power supply line ( l1)-Discharge lamp (1)-Primary side (L1) of current transformer (CT)-Switching element (5)-Power source (AC) flows through the path of power line (l2) and turns on the discharge lamp (1), After that time, the next morning, Since the switching element 5 is turned off because the trigger signal at (9) is not output, the power supply line l1-the circuit breaker 2-the primary side L2 of the current transformer CT-the primary side L2 of the transformer PT. Although the closed circuit of the path of the capacitor C1 is formed, the capacity of the capacitor C1 is not enough to turn on the discharge lamp 1, so that the discharge lamp 1 is turned off.

In the present invention, in order to control the power supply by the drive circuit unit 13 connected to the output terminal of the calendar timer circuit unit 9 and the switching element 5 of the switching circuit unit 6, a discharge lamp such as a security lamp or a street lamp ( 1), a capacitor C2 for improving the reverse is provided. If the ballast coil CO1 of the discharge lamp 1 is disconnected or the lamp is disconnected, only the power factor improving capacitor C2 becomes a load. Since the load of 5) becomes capacitive, the switching element 5 cannot be triggered by the pulsed trigger method. Therefore, in the present invention, in order to trigger the switching element 5 more effectively, the drive circuit part 13 composed of a triac driving photocoupler is adopted to drive the switching element 5 in a stop switch method.

That is, the trigger signal output of the calendar timer circuit unit 9 is hundreds of cycles and is output in a switching pulse type of duty ratio 1/3 to 1/5, and this signal is output at 2V, several tens of microseconds at the diode D1 and the flat capacitor C. By converting the DC signal into a trigger signal and inputting it to the gate terminal of the switching element 5, the stop switch operation is performed at a drive output of 1/3 to 1/5 of the DC output, thereby stably switching the capacitive load. .

In addition, the present invention is a date and time setting that anyone can set or adjust the current month, day and time of the calendar timer circuit unit 9, which has been input and memorized for 365 days (1 year) in advance of morning and evening The display circuit unit 10 is provided.

The date and time setting display circuit section 10 includes a digital display section D for displaying the month, day, and time of the current operation, and a function selecting switch SW1 that is two operation switches for ease of configuration and operation. , Month, day, hour, minute hour. The counter has a count setting switch (SW2) for shifting and counting up each time the number is pressed. The digital display unit (D) has a function indicator (D1) and a month, day, hour, and minute. The data display D2 and the like and a driver D3 for driving each display are constituted.

The date and time setting display circuit unit 10 of the present invention is in a blank state in which no display appears on the digital display unit D at an initial state, and then presses the function selecting switch SW1 once. The output appears on the display, indicating that "1" is displayed on the function indicator (D1) and the control mode is entered. Whenever the counter setting switch (SW2) is pressed, the discharge lamp (1) turns on and off alternately manually. At this time, even during the lighting time of the discharge lamp 1, the calendar timer circuit 9 is in a standby state, and the ON / OFF operation of the switching element 5 is switched to the manual control state. The circuit unit 13 does not operate and thus the switching element 5 is also cut off so that the discharge lamp 1 is switched off, thereby reducing unnecessary waste of power consumption during operation. The load on the power generator and the switching circuit 6 is reduced.

In this state, pressing the function selection switch SW1 again (corresponding twice) displays the number "2" on the function indicator D1, and the "current month" on the data indicator D2. When the displayed month is different from the current month, press the count setting switch (SW2) to adjust the "month", then press the function selection switch (SW1) again (corresponding to three times). Day "appears, and in this way, pressing the function selection switch SW1 four times means the" current time "is pressed five times and the function selection switch SW1 is pressed. SW1) is pressed 6 times to turn on today. Pressing function selection switch SW1 7 times to turn on today. Pressing function selection switch SW1 8 times to turn off today. Pressing the function selecting switch (SW1) nine times will display "lights out of the day" so that the current state can be displayed and identified. If necessary, press the count setting switch (SW2) to adjust each function.If the function selection switch (SW1) is pressed 10 times or a few minutes have elapsed after the last press, the function returns to its original operating state. Each of the switches SW1 and SW2 described above is installed outside the base as shown in FIG. 2 to set or adjust the time of inspection, lighting, lighting, etc. as necessary.

Therefore, if the current month, day, hour, minute, etc. are set and adjusted, and the month, hour, and minute are reached, the morning and evening hours are remembered 365 days according to the morning and evening times of the corresponding month and day. The calender timer circuit 9 outputs the output at the corresponding time to control the switching element 5 through the drive circuit 13 to turn on or off the discharge lamp 1.

In addition, the present invention is provided with an automatic off detection circuit unit 11 for turning off the discharge lamp (1) according to the ambient brightness to prevent the discharge lamp (1) is turned on during unnecessary day time.

The automatic motion detection circuit unit 11 is configured as an enable switch to enable the CdS operation of the photosensitive capacitor CdS. When the surroundings are considerably bright, the photosensitive capacitor CdS operates so that the calendar timer circuit unit 9 The output disappears so that the trigger signal through the drive circuit 13 does not appear and accordingly the switching device 5 operates so that the output of the calendar timer circuit 9 disappears so that the trigger signal through the drive circuit 13 does not appear. As a result, the switching element 5 is not operated, and the discharge lamp 1 is turned off, thereby preventing lighting cases in unnecessary situations. The calendar timer circuit 9 has a power failure compensation clock generator 12. Is added to eliminate the time error during power outage and to reduce the burden on the battery (BATT).

That is, a power failure or breaker 2 is applied to the calendar timer circuit unit 9 operating by inputting a commercial frequency of 60 Hz induced on the secondary side of the current transformer CT and the transformer PT of the power generation and switching circuit unit 6. When the power supply is cut off and the power supply is not made after a certain time, the power failure compensation clock generator 12 operates to oscillate a 1 Hz oscillation signal and input it as a reference time signal of the calendar timer circuit unit 9, in this case, the calendar. The timer circuit 9 is in the automatic standby state, and only exhibits an input signal count function of 1 Hz, but other circuits do not operate, thereby preventing excessive consumption of the emergency power charged in the battery. Will reduce.

In this configuration, the present invention is connected to a two-wire power supply in series with a discharge lamp so that the operating power of the necessary equipment can be supplied at any time regardless of whether the discharge lamp is turned on or off. The discharge light can be turned off and on according to the time schedule of the morning and evening night hours according to the 365 days of the year, and can be turned on and off exactly at the required time, and also by two simple external operation switches. It is easy to set up and change the off time and turn off the lights, so that any residents can operate it correctly by simply setting the time, so that inconvenience and complaints caused by the malfunction can be eliminated. It can be turned off without any concern for It can be economically effective in terms of maintenance, etc., and it is useful to have the effect of simply installing anyone by simply replacing the existing manual switch by connecting and connecting it in series to the power supply 2 strands. It is an idea.
